PAPER FOR MAKING TRANSFER-PlCTURES.

SPECIFICATION forming part of Letters Patent No. 504,835, datedSeptember 12, 1898. Application filed February 9, 1893. Serial No.461,666. (No specimens.)

To aZZ whom it may concern:

Be it known that I, Hnoron DE GRoUsIL- LIERS, a subject of the GermanEmperor, and a resident of Berlin, Germany, have invented certain newand useful Improvements in Paper for Making Transfer-Pictures, of whichthe following is a specification.

The presentinvention consistsin applying to the transfer paper a coatingsoluble in water, and a second coating of a material insoluble in water,which serves to carry the impression of the design, and which afterremoval of the paper, is applied with the impression uppermost, to theobject to be decorated, upon which it is then pressed by means of a softbrush. After drying, this skin adheres perfectly to the decorated objectand the design can be burned in if the colors are of a vitreous nature.

The design is first printed or formed on the soluble coating and whenthe insoluble coating is applied it receives the impression thereof onits inner face which when the outer face is pressed upon the surface tobe ornamented and the paper and soluble coating is removed becomes theuppermost or exposed face of the insoluble coating containing the designand presenting the same to the eye. This insoluble design carrying layerconsists of a mixture of turpentine and a drying oil, which according tothe state of the atmosphere, is mixed with from twenty to twelve timesthe quantity of a two per cent. collodion. The turpentine and drying oilaregenerally used in equal quantities; the proportions have however tobe varied somewhat according to the nature of the printing. Collodionalone, or only mixed with glycerine, for rendering it more supple, canonly be used as the design carrier (as is done with the photo ceramicdusted designs) when the skin has been freshly prepared, because it isvery fragile and diflicult to manipulate. In addition, the skin is veryapt to split off on drying and burning. But in particular the use ofcollodion has the disadvantage that it falls to pieces after a shorttime, and that a design printed thereon can then no longer betransferred. The addition of drying oil renders the skin more supple,tougher-and more dense, and enables it to last a very long time, so thatthe impressions can be kept for a long time. The addition of turpentinerenders the skin more adhesive, so that it adheres veryfirmly to theobject to be decorated. But its particular advantage is that, inpartially evaporating in burning in the design, it renders the skinporous to a certain extent, so that it is not raised off the object bythe pressure of the vapors that may be generated beneath it, and lastly,it melts together on to the object with the residue of the turpentine.

The transfer design may also be prepared according to this invention insuch manner, that design is first printed on the coating soluble inwater, and after the impression is dry, the above described mixture ofturpentine, drying oil and collodion is applied thereto. If the transferdesigns are applied to porous objects, they are apt to split off. Inorder to prevent this, the parts of the object to be decorated are firstcoated with a material that removes the porosity. For this purposetragacanth mucilage, starch paste, turpen tine dissolved in turpentineoil, resin solution, or other suitable material may be employed.

I claim 1. An improved transfer paper, consisting of a base sheet, acoating thereon carrying the design and soluble in water, and a secondcoating covering the first composed of turpentine, drying oil andcollodion, substantially as described.

2. The herein described method of making transfer paper consisting inapplying a coating soluble in water to a base sheet, printing a designon said coating, drying the same and finally applying over theimpression a coating of turpentine, drying oil and collodion,substantially as described.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.
